The Tweets are sent out to twitter for anyone to read. These are public timeline tweets. We are just a twitter client that shows those tweets like any other twitter client, but delayed and using search to figure out what the best tweets to show would be.
When someone Tweets within Tweeplayer during when they are watching it on their DVR at home we are still just sending those tweets out regardless of content, and linking the moment they tweet with the moment they are watching.
We only plan on incorporating public domain or licensed media directly on the site for any full conversation.
